Abstract:
A solid-state fault current limiter including a current splitting reactor, comprising a system current input, a passive current output and a control current output. A voltage control reactor includes a first end and a second end, the first end coupled to the control current output and the second end coupled to the passive current output. A fault current trigger circuit coupled in parallel with the voltage control reactor and configured to open when a fault current, received by the system current input, exceeds a predefined trigger current. A transient voltage control circuit coupled in parallel with the voltage control reactor to receive the fault current.
